【０００１】0001
本考案は枚葉印刷機の排紙部に適用される排紙装置に関する。 The present invention relates to a paper discharge device applied to a paper discharge section of a sheet-fed printing press.
【０００２】0002
図３に枚葉印刷機の一例を示す。この枚葉印刷機は給紙装置１、フイーダボー ド２、２組の印刷ユニツト３および排紙部４よりなり、給紙装置１から出た枚葉 紙はフイーダボード２より最初の印刷ユニツト３ａに入り、この印刷ユニツト３ ａの圧胴５ａとブランケツト胴６ａとの間で印刷され、圧胴５ａより中間胴７を 経て、最終の印刷ユニツト３ｂの圧胴５ｂとブランケツト胴６ｂとの間で印刷さ れ、圧胴５ｂより排紙部４の排紙胴８あるいは図４のように２つの排紙中間胴７ ｂを経て排紙胴８に受渡される。 FIG. 3 shows an example of a sheet-fed printing press. This sheet-fed printing machine has paper feeding device 1, feeder board It consists of a board 2, two sets of printing units 3, and a paper ejecting section 4, and the paper sheet output from the paper feeder 1 is The paper enters the first printing unit 3a from the feeder board 2 and is transferred to the first printing unit 3a. Printing is performed between the impression cylinder 5a and the blanket cylinder 6a, and the intermediate cylinder 7 is printed from the impression cylinder 5a. After that, printing is performed between the impression cylinder 5b and the blanket cylinder 6b of the final printing unit 3b. From the impression cylinder 5b, the paper discharge cylinder 8 of the paper discharge section 4 or the two paper discharge intermediate cylinders 7 as shown in FIG. The paper is delivered to the paper discharge cylinder 8 via the paper transfer cylinder 8.
【０００３】 図２のように排紙胴８の両側にはそれぞれスプロケツトホイール９が取付けら れていて、これらスプロケツトホイール９に駆動されるチエーン１０の間に渡っ て設けられたチエーングリツパ１１が走行している。紙は圧胴５ｂ又は排紙中間 胴７ｂ（以下代表して圧胴５ｂとする）の爪１２よりチエーングリツパ１１の爪 １３に点Ａにて受渡される。この時排紙胴８の中心よりｒの距離にあるチエーン グリツパ１１の爪１３の紙咬え部の角速度をｗとすると、ｒｗの速度にて回転し ている。0003 As shown in Figure 2, sprocket wheels 9 are attached to each side of the paper delivery cylinder 8. The chain 10 is driven by these sprocket wheels 9. A chain gripper 11 installed in the same direction is running. The paper is placed on the impression cylinder 5b or in the middle of paper ejection. The claws of the chain gripper 11 are connected to the claws 12 of the cylinder 7b (hereinafter referred to as the impression cylinder 5b). 13 at point A. At this time, the chain located at a distance r from the center of the paper delivery cylinder 8 If the angular velocity of the paper gripping portion of the claw 13 of the gripper 11 is w, it rotates at a speed of rw. ing.
【０００４】 爪１３にて咬え替えされた紙は排紙部４の積載部１４にて行われる紙の蓄積の 性能を向上する目的で、スプロケツトホイール９より外れたチエーンガイド１５ にて案内し始める点Ｂで減速されるようにスプロケツトホイール９の直径（２ｒ a ＝Ｄa ）が圧胴５ｂの直径Ｄより少なくしてある。よって点Ｂよりチエーング リツパ１１の走行速度はｒa ｗとなり速度差はｒｗ−ｒa ｗとなる。0004 The paper that has been replaced by the claw 13 is stored in the stacking section 14 of the paper discharge section 4. Chain guide 15 removed from sprocket wheel 9 for the purpose of improving performance. The diameter of the sprocket wheel 9 (2r a =Da) is smaller than the diameter D of the impression cylinder 5b. Therefore, chaining from point B The running speed of Ritzpa 11 is raw, and the speed difference is rw-raIt becomes w.
【０００５】 尚圧胴５ｂよりチエーングリツパ１１に紙を受渡す時は点Ａにおける両部材５ ｂと１１との角速度および爪１２と１３の周速は同一の為、紙は円滑に受渡され る。[0005] When transferring paper from the impression cylinder 5b to the chain gripper 11, both members 5 at point A Since the angular velocity of b and 11 and the circumferential velocity of claws 12 and 13 are the same, the paper is transferred smoothly. Ru.

スプロケツトホイールの径が圧胴の径より小さいためチエーングリツパがスプ ロケツトホイールより外れ、チエーンガイドにて案内され始めるＢ点にて減速（ ｒa ｗ）されるので、チエーングリツパがスプロケツトホイールにて駆動され圧 胴の周速ｒｗにて走行していた紙の紙尻部分がその慣性によりチエーングリツパ の爪にて咬えられている紙の前端方向に送られ紙全体がたるみ紙の挙動が不安定 となる為紙破れ、傷入等の不具合が生ずる（図２で一点鎖線にて示すように紙が たるむ。） 本考案はかかる問題点に対処するため開発されたものであってチエーングリツ パがスプロケツトホイールより外れ、チエーンガイドに案内され始める点Ｂの周 速を同一にすることを目的とする。Since the diameter of the sprocket wheel is smaller than the diameter of the impression cylinder, the chain gripper comes off the sprocket wheel and is decelerated (r a w) at point B where it begins to be guided by the chain guide, so the chain gripper is driven by the sprocket wheel. The trailing edge of the paper, which was traveling at the circumferential speed rw of the impression cylinder, is sent toward the front end of the paper gripped by the chain gripper's claws due to its inertia, causing the entire paper to sag, making the behavior of the paper unstable. As a result, problems such as paper tears and scratches occur (the paper sag as shown by the dashed line in Figure 2). The purpose is to equalize the circumferential speed at point B, which comes off the chain guide and begins to be guided by the chain guide.
【０００７】[0007]
上記の目的を達成するための本考案の構成を実施例に対応する図１を用いて説 明すると本考案は排紙胴８の両側に取付けられるスプロケツトホイール９の径を 、前記排紙胴８に当接する圧胴５ｂ又は排紙中間胴７ｂの径と同一としたことを 特徴とする。 The configuration of the present invention for achieving the above purpose will be explained using FIG. 1 corresponding to an embodiment. To be clear, the present invention is based on the diameter of the sprocket wheels 9 attached to both sides of the paper delivery cylinder 8. , the diameter is the same as that of the impression cylinder 5b or the intermediate sheet discharge cylinder 7b that comes into contact with the sheet discharge cylinder 8. Features.
【０００８】[0008]
そして本考案は上記の手段によりスプロケツトホイールにより駆動されるチエ ーングリツパの走行速度と、圧胴又は中間胴の周速が同一なので、これら両部材 の速度差はなくなり、従来のようにチエーングリツパが減速を始めるＢ点で発生 していた紙全体のたるみがなくなる。 The present invention also provides a chain driven by a sprocket wheel by the above means. Since the traveling speed of the ring gripper and the circumferential speed of the impression cylinder or intermediate cylinder are the same, these two members The speed difference disappears and the chain gripper starts to decelerate as before at point B. The slack in the entire paper that was previously used is eliminated.
【０００９】[0009]
以下本考案の一実施例を図１に基づいて説明すると５ｂは圧胴、８は排紙胴、 ９はスプロケツトホイールを示し、該スプロケツトホイール９の径Ｄは圧胴５ｂ の径Ｄと同一とした。 かくてスプロケツトホイール９にて運ばれるチエーングリツパ１１の走行速度 は圧胴５ｂの周速と同一になり、チエーンガイド１５にて案内され始める点Ｂで も圧胴５ｂの周速と同一である。 An embodiment of the present invention will be described below based on FIG. 1. 5b is an impression cylinder, 8 is a paper discharge cylinder, 9 indicates a sprocket wheel, and the diameter D of the sprocket wheel 9 is equal to that of the impression cylinder 5b. The diameter was set to be the same as the diameter D. Thus, the running speed of the chain gripper 11 carried by the sprocket wheel 9 becomes the same as the circumferential speed of the impression cylinder 5b, and at point B where it begins to be guided by the chain guide 15. is also the same as the peripheral speed of the impression cylinder 5b.
【００１０】 尚、チエーングリツパ１１の走行速度と圧胴５ｂの周速は同一になることが好 ましいが、経験的には５％程度以下であればよい。0010 Note that it is preferable that the running speed of the chain gripper 11 and the peripheral speed of the impression cylinder 5b be the same. However, empirically, it is sufficient that it is about 5% or less.
【００１１】[0011]
このような本考案によるときは排紙胴に取付けられるスプロケツトホイールの 径を、排紙胴に当接する圧胴又は排紙中間胴の径と同一にしたものであるからス プロケツトホイールにて運ばれるチエーングリツパの走行速度は、圧胴の周速と 同一となり従来のようにチエーングリツパがスプロケツトホイールより外れチエ ーンガイドにて案内され始めるＢ点にて減速されることがないため、圧胴の周速 にてスプロケツトホイールのまわりを回転している紙尻部分が、その慣性により 紙の先端方向に送られ紙全体がたるむことがないので紙破れ、傷入り等の不具合 を防止できる効果を有する。 When using this invention, the sprocket wheel attached to the paper delivery cylinder is The diameter is the same as the diameter of the impression cylinder or intermediate cylinder that comes into contact with the paper delivery cylinder. The running speed of the chain gripper carried by the pro-ket wheel is the circumferential speed of the impression cylinder. The chain gripper comes off from the sprocket wheel like before. Since the peripheral speed of the impression cylinder is not decelerated at point B where it begins to be guided by the Due to its inertia, the tail of the paper rotating around the sprocket wheel Since the paper is fed toward the leading edge of the paper so that the entire paper does not sag, problems such as paper tears and scratches occur. It has the effect of preventing
